Not only DAP and Potaan!I listened to Fiio's "Decision as an earphone brand" "FD7"

■ Decision to solidify the evaluation of FIIO as an earphone brand!FIIO is a popular brand that is highly evaluated in the DAP and portable amplifiers.On the other hand, there was an impression that the evaluation was not keeping up with the ability as an earphone brand until before.Probably, it tends to remain in the perception that "DAP and Potaan brands also have earphones", and it may have been difficult to convey the "seriousness" to the earphones.But now the company is developing a wide range of aggressive lineups.The company has continued to be solid progress and challenging evolution, and as a result, the company's evaluation is being established in the field of earphones.There will be quite a few earphone fans who feel so.The new product "FD7" (around 79,000 yen including actual sales tax) that appeared at such a timing can be a model that can be a "decisive hit" that will further solidify its high reputation.■ Pure Berrillium diaphragm is amazing!In the company's lineup, the model number of "FD" represents a single dynamic driver configuration model, probably based on FIIO Dynamic.This FD7 is the latest and high end.The first thing to keep in mind is the use of a 12mm diameter "Pure Berrillium" diaphragm.Of the elements required for the diaphragm, the characteristics of the main metal material are compared to the focus on the speed that does not transform according to the movement, the lightness that increases the response to movement, and the speed of conveying vibration.However, the berrillium is overwhelmingly stubborn, faster than titanium, but a speed of conveying the sound, and a light specific gravity.The adoption of such excellent materials leads to acoustic dominance.What I want you to pay attention to is the "pure" part of the "pure berrillium" diaphragm.The "pure" attached here generally means "pure berrillium that is not an alloy with other metals", but in the earphone diaphragm, there is another "resin and other resin, etc."Instead of applying, the meaning of the beryllium material itself is also added.Or rather, that meaning will be pushed more strongly.This is because there are currently many cases of adoption if it is a diaphragm with a bellium coating on PET resin.In the FIIO lineup, for example, the entry model "FD1" that costs less than 10,000 yen.On the other hand, there have been examples of adoption of diaphragms only by bellillium itself.However, it is mainly about the "super" high -end price range that costs 200,000 yen.Berrillium has a remarkable processing, and it is not easy to form a precision as an earphone diaphragm.In other words, considering the development and manufacturing costs, that is also reasonable.However, this "FD7" is less than 80,000 yen, using its pure berrillium diaphragm.Exceptional!Not just pure -belillium diaphragm!Innovative sound design ■ Pure Berrillium diaphragm, not just!However, if it uses a sound design unique to FIIO, it is amazing if it is just a pure -berrillium diaphragm (cheap), but it is not unique to FIIO.What are the pure -berrillium diaphragms, and there's a cheaper earphone.It is the greatness and charm of FD7, "FIIO has a dynamic earphone technology unique to FIIO, and it was created by the merging of a piece called Pure Verillium diaphragm.It is the ultimate form of dynamic earphones.The dynamic earphone technology unique to FIIO is also a distinctive factor in the adoption of a semi -open structure, including the "acoustic prism system" and the "bolkanic field mechanism".They were first installed in the "FD5" released earlier this year and were introduced as "innovative breakthroughs on acoustic design."In other words, as a large frame, it can be called "FD7 that inherited the basic elements of FD5, but that the fd5 was a pure-verillium diaphragm that used to be a berrillium coating edge & diamond-leaf carbon diaphragm."What I would like to mention here again is that the conventional model FD5 had already hit a wonderful sound at that point.This shows that the splendor of the FD7 sound is not only for pure -berrillium diaphragm.Rather, I even feel that the unique elements of FIIO can fully draw out the charm of the pure -verillium diaphragm.■ What is "innovative breakthrough about acoustic design"?By the way, as mentioned above, he explained that the "dynamic earphone technology unique to FIIO" used in FD7 is the adoption of a semi -open structure, as an acoustic prism system and a bolkanic field mechanism.Let's check again.The "Acoustic Prism System" is a mechanism that is placed between the front of the diaphragm and between the diaphragm and the sound conductor, and has the role of controlling the way of transmitting the sound waves in the sound of sound.The effect is to eliminate high -frequency -specific waves and improve sound diffusion.In speakers, it is described as applied to the earphones of the "diffuser" ideas placed on the front of the tweeter unit.Conversely, the Volcanic Field Mechanism is located on the face plate side on the back.This is described as a "volcanic -shaped diffuser", and seems to be a mechanism that properly controls the air flow and pressure on the back of the driver.It is said that the effects are reduced in low -frequency waves and distortion, and improvement of low -frequency diffusion.And this unit adopts a semi -open structure.With canal -type earphones, port equipment for moderately removing air pressure in the housing is not unusual.But FD7 is a more aggressive semi -open structure that is different from the port of that kind.That is why it is also claimed in terms of design that "semi -opening is the feature of this earphone!"Even though it is a cicada, it is an open type, so it is undeniable that the sound leakage is larger and the sound insulation is lower than that of the completely sealed structure, and some people think that it is a weak point.However, in the current situation, isn't it a lot of users who think it's not a problem?It depends on each way and listening style, but "The problem with sound leakage and sound insulation is when you use it outside, but listening to music outside has already switched to a complete wireless, so the high -end earphones are high -end earphones.There should be many people who say that if you listen to music carefully at home, you can demonstrate your true territory! "Other notable points are "Sound control mechanism by replacing sound path pipes", as in FD5, and "2) by licensing from Fabrilous..5/3.5/4.4mmプラグ付け替え機構」も引き続き採用する。音導管は、FD5では2タイプ付属だったところを、こちらでは3タイプに。この手のチューニング機構では、音導管に仕込まれたフィルターによって、音を調整する仕組みのものが多いかと思う。だがこちらのシリーズでは、主に音導管の内径の太さによって、音響を調整するとのことで、径の大きい音導管は空間の広さ、小さい音導管は低域重視、中間はバランス重視となっている。気になるサウンドをチェック！■ギター名演の演奏ニュアンスに、完璧に追従する超レスポンス！それではいよいよ、試聴レポート！組み合わせるプレーヤーには、Astell&Kern「SA700」を使用した。繊細な表現を得意としつつ、駆動力にも不足はないDAPだ。まずは、最もスタンダードで中間的な組み合わせと思われる、「バランスタイプの音導管／バランスタイプのイヤーチップ／3.From the setting of 5mm single end drive.Then, I started listening to the cover song "Just the Two of US" by Jose James.■ Jose James "Just the Two of US" ... Yeah.With this setting as the starting point, I was going to change the settings from there and tell me the process of driving it to my liking, but I suddenly received a favorite sound.Listening, the bandwidth balance is almost perfect.It is a really stunning balance to both ends in the ultra -low and ultra -high range, and there is no habit of swelling in the mid -low range and peaks in high frequencies.For example, the atmosphere in which the sound of the bath drum resonates as an air from low to ultra -low range is also firmly reproduced.There are many audios that cannot be reproduced at all, lifting the center of gravity in the middle range, and making them sloppy, but this earphone can do it accurately.The feel of the sound is also impressive.Although it has a slightly hard tendency, it does not have a crushed and smooth hardness, and also has a rich touch and feel of smoothness and moistness.When you listen to the voice and vocals of people, the feel is particularly easy to understand.Also, I think it's a good idea to look at the cymbal while imagining the dull metal touch.Like this song, a high -quality recording will be a subtle particle with a slight metal quality and a sound like a metal powder.In scenes where the tone of the sparkling electric piano fluctuates, the high level of spatial expression was also shown.It's too sensitive, but somehow, the way the sound is placed feels like "it was naturally placed in a space where there was plenty of space" instead of "it was placed in a limited space".That's it.It is not just because it has a semi -open structure, but there is no doubt that those who expect a semi -open space expression to be a semi -open space will be satisfied.In addition, the impact of listening to Joe Pass's solo guitar performance "How High the Moonon" was strong.This work is a record of raw sounds that do not pass through the amplifier of a full -coated guitar, and it is a rare performance -centered performance, which is rare for this kind of solo guitar, and has a strong touch of performance.Listening to it with this earphone, the dynamics and variations of how to pick the strings, this sound is played with a pick, and that sound is played with your fingers, and the sounds out of the right hand picking., Swell by mixing the sounds out of the left hand finging ... The performance nuances unique to all guitars reach the wonderful arrival.Many of these nuances are strong in the attack part of each sound.The fact that it "reaches" means that this FD7 is extremely excellent in the reproducibility of the attack.The response to input is fast and accurate.This point can be imagined that the contribution of the pure -verillium diaphragm is particularly large.As represented by this song, it is outstanding with the guitar music in general, which is a tone close to a clean tone and has a rich touch!I would like to inform you strongly.In addition, Jimi Hendrix "Little Wing" was also the best.Verify the combination of sound conductor / earpiece!■ Tuning with sound guidance pipes and earpieces By the way, I was very satisfied, but I was very satisfied, but I also introduced tuning by replacing the sound conductor and ear chips.Let's do it.The following three types are included as described above.● Inner diameter large/green: Excellent in the details of the ultra -high range ● Inner diameter/black: Balanced sound ● Inner diameter small/red: Powerful bass is a strong bass.The difference is not extreme, it seems to be easy to use for space expression and delicate fine adjustments, "" Inner diameter small is pushed in the middle and low races easier to understand and obtain clear effects compared to the inner diameter and large. "The ear chips are also included.Each shape, material, and large and small inner diameter are different, and this can also be used for tuning.The details are as follows.● BASS ● VOCAL ● Spinfit ● Memory Foam (form material) ● Balanced ● Tri-FLANGE (3-stage umbrella) However, it is also important to wear in eartips.Considering the tuning of the sound, you can't choose an ear chip.Therefore, it is recommended that the roles are based on the roles, such as "adjusting the sound mainly by selecting the sound conductor, and choosing the ear chips."Being able to share such a share is also an advantage of a model with a sound conductor exchange organization.However, there is one precautionary point in choosing this sound conductor and ear chips.Since the inner diameter of the small pipes of the inner diameter is not only the inner diameter but also the outer diameter, only the triple flange is exactly the same as the attached eartips.The intention of the design is that in the description of the triple flange support page, "A small sound tube that can insert it deep into the exterior and leads to a richer sound. If you use this ear tip, the red ring is thin.As you can imagine from the sentence, "Please use the replacement type sound conductor", the inner diameter of the small inner diameter has a triple flange ear chip.Perhaps it is a sound conductor prepared for users who want to use the ear chips.However, the higher the degree of freedom of the combination of sound conductors and ear chips, the higher the higher the degree of freedom.In the future, I would like to expect items such as the thickness of the inner diameter, the thickness, and the outer diameter that is aligned with the others, and an adapter for adjusting the outer diameter.■ FIIO earphone's masterpiece!So there is such a detailed request, but there is only such a request.In the first place, I am very satisfied with the combination of balance sound guidance and balance ear chips, so I do not really care about the trivial weaknesses of other sound conductors.Speaking of the strong and precautions, the borrowed listening machine had a sticky note of "400H aging".Before demonstrating the ability, there is a sign that sufficient driving is needed.In general, the harder diaphragm tends to make time to sound, so when listening or purchasing this unit, it seems better to keep that in mind.This FD7 is a model that has perfectly responded to its expectations.FIIO's earphones are now at this level!I want you to experience that.◇◇◇ Atsushi Takahashi takahashi, atSushi Hobbies and work are created.The creation of sentences as a job is mainly related to audio.Other hobbies include reading, listening to music, watching animation, watching movies, playing and maintenance of electric guitars, and cats.He is active every day, making use of his hobbies for his job and making use of his work as a hobby.
